PINK, OF CAMBRIDGE, MARYLAND, ASSIGNOR TO THE CAMBRIDGE WIRE CLOTH COMPANY, OF CAMBRIDGE MARYLAND TIE-ROD FOR WIRE-FABRIC BELTS Application filed March 14, 1930. Serial No. 435,923.

This invention relates to improvements in wire fabric, such as that forming the subjectmatter of my Patent No. 1,707,567, dated April 2, 1929, the general object of the invention being to provide tie rods for holding the sections of the fabric together to prevent the sections from spreading apart, as it has been found that a belt constructed of sections, the spirals of which are alternately arranged, has

a tendency to spread, which eventually results in the tearing of the fabric. Thus in order to prevent this spreading of the belt or fabric, tie rods are transversely arranged in the fabric and connected with the same so as to prevent this tendency of the belt to spread.

The invention is also capable of use with fabric formed in transverse sections, in which the alternate sections have the helicals extending to the right and the remaining sections have the helicals extending to the left. Thus the invention is applicable to wire fabric composed of longitudinally extending sections as well as fabric composed of transverse sections.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or correspondin parts throughout the several views,

and in w 1611 Figure 1 is a fragmentary view of the face of the improved fabric,

Figure 2 is an edge view,

Fi ure 3 is a section on line 3-3 of Figure 1, and

Figure 4: is a Figure 1.

The invention is shown and described as used with a belt or fabric in which the sections are longitudinally arranged, as described in my before-mentioned patent, but as before stated, the invention can also be used with a belt or fabric in which the sections are transverselyvarranged.

Referring to section on line 44 of igure 1, the letter A indicates tions of the adjacent members. The helical.

members of one section are reversely arranged to those of the other section so that the outer and inner ribs formed by the outer portions of the convolutions extend in an opposite direction from the ribs of the other section. This arrangement prevents any tendency of the belt to creep sidewise on the drums or pulleys, as the members of one section tend to move in one direction, while the members of the other section tend to move equally in an opposite direction. This tendency of the two sections to move apart causes the belt or fabric to spread so that it is increased in width and eventually this spreading results in the tearing of the fabric. In order to prevent this disadvantage, I provide a plurality of rods 3 which extend transversely through the belt or fabric, with the ends of the rods connected with the ends of some the helical members, as shown at 4. Each rod also asses between the ends of the convolutions of a pair of the helical members.

Thus these rods fasten the parts together in such a manner that the tendency of the belt-or fabric to spread is prevented and thus the rods prevent any change in the width of the fabric.

If desired, the rods may be connected to intermediate portions of the helical members, as shown at 2'.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is I 1. A wire fabric composed of longitudinally eXtendin sections, each section comprising helical mem bers and each member having the ends thereof secured to the ends of the adj acent member, the diagonally. arranged ribs formed by said members extending in one direction in one section and in an opposite direction in the other section, and rods passing through certain of the helical members and having the ends thereof secured to the ends of the respective members where the latter are secured together and secured to certain other portions of the members whereby spreading of the fabric is prevented.

2. A wire fabric composed of sections, each section comprising helical members and each member having the ends thereof secured to the ends of the adj acent member, the diagonally arranged ribs formed by said members extending in one direction in one section and in an opposite direction in the other section, and rods passing through certain of the helical members and having the ends thereof secured to the ends of the respective members where the latter are secured together and secured to certain other portions of the members whereby spreading of the fabric is pre vented.

In testimony whereof I affix my signature.
